KnowWare International Inc. announces the addition of a capability analyzer to the QI Macros SPC (statistical process control) software for Excel. Manufacturers seeking to measure the quality of their product can now analyze up to eight characteristics for a single part simultaneously. KnowWare has also created a standalone dashboard including control charts, histograms and a normal probability plot for each of the eight characteristics.



Cp is a measure between 0 and 2 that evaluates how well the manufactured parts will fit between the customer's specification limits. A Cp measure of 1.0 equates to 3 sigma; 1.33 equals 4 sigma; 1.66 equals 5-sigma; and 2.0 equals the infamous Six Sigma. Cpk measures how well the product is centered between the limits. The Cp and Cpk tool also measures Pp and Ppk which are measures of total process performance.



The QI Macros are an add-in for Microsoft Excel that automate all of the charts and diagrams required for statistical process control (SPC) and Lean Six Sigma. There are over 70,000 registered users. The QI Macros are used by over 2,700 hospitals and medical centers to hold down costs and increase health care quality. The QI Macros consist of three parts:



1. Macros that use existing Excel data to create 18 different charts: line, run, pareto, control charts, and histograms.

2. Fill-in-the-blank templates, over 40 in all, for flowcharts and fishbones, design of experiments (DOE), quality function deployment (QFD), and GageR&R studies.

3. Statistical analysis tools like ANOVA, f-test, regression, and a sample size calculator.



Unlike complex statistical tools, the QI Macros tools can be used by anyone from nurses to Six Sigma Black Belts. Users most often say that the QI Macros are:

·Easy to learn. The pull-down menu gives immediate access to all tools.

·Works directly on Excel data. Over 90% of the world's offices use Excel. With the QI

  Macros, there is no need to transfer the data out of Excel. Just select and go.

·Automates the most commonly used Improvement tools.
